Everything you need to know about our 3D online tabletop RPG platform, answered clearly and directly.
Erderon will be a complete online tabletop RPG platform that already features an immersive 3D grid, a ready-to-play medieval world and professional monthly adventures. Unlike other VTT platforms on the market, Erderon delivers an entire universe, not an empty table waiting for you to build everything from scratch.
After more than three years of development, we launched the pre-alpha in March 2026. The core idea was born from a real frustration: to play RPG online today, a game master needs a voice app, a VTT for the grid, another for character sheets, bots or YouTube for sound effects, PDFs for the adventure, third-party tools for miniatures. The result is a "Frankenstein" of platforms that breaks immersion at every turn. Erderon eliminates that problem and unifies everything. The game master transitions from exhausted builder to epic story director; the player from frustrated to fully focused. The world is already built. The adventures are already ready. You just show up and play. But if you want to run your own adventure, you can do that too!
Erderon is for game masters who spend 10, 15, 20 hours a week preparing sessions; for players who want real immersion without switching between five windows; for aspiring GMs. It is the most streamlined and complete entry point on the market.
I have been GMing for 22 years. The feeling of spending more time building maps, history and lore than actually narrating and directing stories is the problem the platform solves. Here, if I want, I can start an adventure in 30 minutes and players stay focused from beginning to end. Erderon serves four main profiles:
No. Erderon does not try to replace those tools. It serves a different audience: GMs who prefer to direct a story rather than build every element from scratch. Healthy coexistence is the goal. Each tool has its own purpose.
Other VTT platforms are excellent for those who want to create their own world and have plenty of time to do so. Erderon serves those who prefer the opposite path. The online RPG market grows more than 20% per year and there is plenty of room for multiple tools with distinct approaches.
Choose Erderon if you want:
Other tools may be more suitable if you want:
Yes, partially. There is a free tier that gives access to the platform, the first official adventure and the first lore document, at no cost and with no expiration date. To access the second adventure and second lore onward, a paid plan is required.
The free tier is not a trial with a countdown. It is a permanent access level designed so that anyone can explore the Erderon universe and play a full session before deciding to subscribe. Paid plans, billed via Stripe directly on the site in BRL or USD, unlock the continuous flow of new monthly adventures and lore. Erderon is an independent project with no outside investors, and each subscriber directly funds development and monthly deliveries.
Not today. Players join any session hosted by a GM for free. They only need to create a free account on the site.
The platform is open to everyone. Just create your account and get access to the platform download in the member area. Inside it, the GM can choose one of the available adventures for their session. If they want to go deeper with the full adventure and detailed lore, they support the project and receive access to the downloadable materials. The more support we get, the further we can develop the project.
The pre-alpha launched in March 2026 includes a functional 3D grid, an interactive map of the Nororsaer continent, an integrated dice system and two professional adventures: Omens — The Comet (March) and Omens — A Light Rain Over Stone (April). A relaunch with significant improvements is planned for May 2026.
What is already available:
Yes. Erderon delivers the 3D grid, the map, the dice, the adventure, integrated voice and a basic level 1 character sheet. For video, an external tool is still required in this phase. Full character sheet automation and integrated video are coming in version 1.0.
Groups are already running successful sessions with this setup in the pre-alpha. Even with the tools partially separated, the experience is already notably more immersive than other VTT platforms with 2D grids. The main advantage Erderon delivers right now is the 3D environment, a ready-made professional adventure and the interactive lore map, without having to build anything.
Omens — The Comet is Erderon's first official adventure, created and hand-drawn by the team. All artwork is made by human artists with no use of artificial intelligence. It is a ready-to-play adventure with unique NPCs, ready-to-use combat grids and lore connected to the Erderon universe.
This adventure sets the quality standard Erderon commits to maintaining in all monthly releases. It includes detailed scenes with narration-ready descriptions, balanced combat encounters, NPCs with their own personalities and motivations, and narrative hooks that connect to the greater lore of the continent. The adventure is set in the period just after the passage of the Red Tail Comet, when magic begins to return to the world of Erderon.
No. Erderon was built so that any GM, with zero technical knowledge, can start a session in minutes. There is no server configuration, no router port forwarding and no module installation required.
This ease of use is a direct differentiator from other VTTs on the market. In Erderon, hosting is free, included for all registered users and managed automatically by the platform. You create the account, load the adventure, invite players with a link and start. The time between "I just created my account" and "my session is happening" is minutes, not hours.
The lore documents are monthly story collections narrated in first person by a sage of the realm who travels the continent, recording places, characters and events with hand-drawn illustrations. The first lore is available to everyone, including the free tier. The second onward is exclusive to Cavaleiro and Lorde tiers.
Each volume follows this sage through a different region of the Nororsaer continent, expanding the universe with details that don't appear in the adventures: the architecture of a city, the customs of a faction, historical records of past events. Illustrations are hand-drawn by Erderon artists with no use of artificial intelligence. The Batedor tier receives monthly adventures but not lore documents from the second onward. Cavaleiro and Lorde accumulate adventures and lore month after month.
A new professional adventure is released every month for all subscription tiers. An exclusive lore document is also delivered monthly, for Cavaleiro and Lorde tiers only. The cadence started in March 2026 and does not stop.
The monthly cadence is a core commitment of Erderon, not just a promise. The content calendar is planned months in advance by the creative team. Adventures are part of campaigns with narrative continuity, meaning each adventure delivers the hook for the next. Subscribers who join after the campaign has started have access to all previous adventures included in their tier.
In the pre-alpha, character creation is available for Human and Elf, with an initial set of implemented classes. Full support for all races and classes from the SRD 5.5e will arrive progressively, possibly before the final 1.0 release.
The initial selection covers the most common races at D&D tables and serves to validate the creation system before expanding to the full catalog. The automatic character sheet, with all D&D 5e mechanics calculated in real time including attributes, modifiers, initiative and hit points, is one of the central pillars of version 1.0.
Yes. Erderon is 100% focused on D&D 5.5e in the current version, using the SRD (System Reference Document) rules under Creative Commons CC-BY-4.0 license. All adventures, combat mechanics and automations follow the official 5.5th edition rules.
The SRD 5.2.1 is the official document containing the core rules of D&D 5.5e, now available under Creative Commons license, which allows use, adaptation and publication with attribution. This means all the mechanics players already know, including turn-based combat, ability checks, saving throws, spells and conditions, work exactly as in the original system.
Not yet. The current version and 1.0 are exclusively for D&D 5.5e. Support for other systems is on the roadmap for version 2.0, with priority for Ordem Paranormal, Vampire: The Masquerade, Pathfinder 2e, Call of Cthulhu and Tormenta 20.
The decision to start with a single system is not a limitation, it is strategy. Doing D&D 5.5e flawlessly, with complete automations and high-quality adventures, is more valuable than supporting ten systems poorly. Once version 1.0 is consolidated, expansion to new systems will be voted on by the community.
The current version runs on Windows 10 and 11 only. Support for macOS and Linux is planned for version 1.0, expected in Q4 2026.
Mac users who want to access the pre-alpha now can run it via Parallels or Wine, but without official team support. Development prioritizes Windows because it is the operating system of the vast majority of online RPG players. The native version for Mac and Linux will arrive in 1.0 without requiring workarounds.
Yes. Erderon operates natively in English since launch. The website and interactive map are already available in three languages: Portuguese, English and Spanish. For subscriptions, Brazilian subscribers are billed in BRL and international subscribers in USD.
The bilingual strategy is a central part of the project. Adventures are created in Portuguese first and translated to English by our CEO, Lucas, not by simple automated translation. As the platform grows, Spanish and other languages will be added to the main interface and adventures as well.
Erderon is a medieval continent where magic was absent for centuries and returned in a chaotic way after the passage of the Red Tail Comet. Sorcerers are feared. Kingdoms compete for power. Adventurers emerge in a moment of deep historical uncertainty.
The continent of Nororsaer was originally colonized by the Styshenos and the Vholgans, who founded the first kingdoms. For entire generations, no common citizen witnessed real magic. The arrival of the Red Tail changed everything: in the months following the comet, reports of witchcraft began, people were burned for casting simple magical tricks, and creatures previously seen only in legends started appearing. Kingdoms established for centuries enter crisis. Old alliances dissolve. New opportunities and new dangers arise simultaneously.
The continent has five main cities in the pre-alpha: Blacksun, Ebonmark, Porto Safira, Hammerhill and Silverwood. Each has its own lore, internal factions, NPCs with history and political connections to the other cities, all accessible through the interactive map.
Blacksun is the largest city-state on the continent, with nearly two million inhabitants, and the biggest trade hub, with low taxes that attract ships from everywhere. Ebonmark, on the banks of the Niudan river, is the capital of the realm of Beryn and the seat of the king. Porto Safira houses the continent's largest library and university, the Lighthouse of Asha'var, 120 meters tall with hundreds of rooms. Each city is mapped in the interactive map with lore markers, political history, local factions and connections to available adventures.
The world has six main factions active in the pre-alpha. Each has its own objectives, loyalties and agendas that cross borders and move pieces on the continent's political board.
Yes. The "Living World" concept is planned for version 1.0: the collective choices of players in adventures will affect the state of the world, and future adventures will reflect those consequences. The world of Erderon is not a static scenario.
The idea is that decisions made in adventures carry real weight. If the majority of tables in a season fail to defend a city, that city falls, and next month's adventures reflect that new state. Global events, wars and political changes become real consequences of campaigns played on the platform.
Both options are valid. The Erderon universe is the default and recommended option, with a ready-made world, lore and adventures. Starting in version 1.0, creation tools will allow building custom worlds, importing maps and writing custom adventures within the platform.
A GM who wants to can use the Erderon universe as a base and modify whatever they prefer, add cities, alter factions or rewrite historical events. Or they can use only the platform (3D grid, dice, sheets) as a tool for a completely custom world. Erderon is first a ready-made world, but the intention is that, in version 1.0, it also becomes a powerful tool for those who want to create.
The subscription is monthly, billed via Stripe directly on the Erderon website. There are three tiers available: Batedor (basic), Cavaleiro (intermediate) and Lorde (premium), with prices in BRL for Brazil and USD for the international market.
The monthly subscription model allows Erderon to deliver new adventures and lore content every month. Unlike software bought once and abandoned, the platform evolves continuously funded by subscribers. There is no commitment contract. You subscribe, try it out and cancel whenever you want.
The free tier gives access to the platform, the first adventure and the first lore. Batedor adds the second adventure. Cavaleiro and Lorde add the second lore and subsequent exclusive content. Each tier is an additional layer on top of the previous one.
The structure was designed so that no one is left out: the free tier already allows playing a full session with a real adventure and real lore. Subscribing to Batedor guarantees access to the continuous flow of new monthly adventures. Cavaleiro and Lorde add monthly lore documents and progressive engagement benefits, including a voice in content votes and access to development behind-the-scenes.
Go to erderon.com, choose the Batedor, Cavaleiro or Lorde tier and click Subscribe. Payment is processed by Stripe directly on the site, in BRL for Brazil and USD for other countries. Access is granted immediately after payment confirmation.
There is no redirection to external platforms or intermediaries. The entire flow happens within the Erderon website. You choose the tier, fill in payment details on Stripe's secure form and receive email confirmation in seconds. After confirmation, access to the platform and your tier's content is released automatically.
Erderon accepts major credit and debit cards via Stripe. Brazilian subscribers are billed in BRL. International subscribers are billed in USD. Bank slip (boleto) is not available at this stage.
Stripe is the payment processor used by platforms like Netflix, Spotify and Nubank. Card data is encrypted and never stored on Erderon's servers. If there is any problem with a payment, you receive an email notice with a grace period to update your details before any access suspension.
Yes. Tier upgrades and downgrades are done directly from your account panel on the site, at any time. The value adjustment is proportional to the remaining period of the current billing cycle.
Upgrading from Batedor to Cavaleiro or Lorde is immediate: access to the new content is released the moment the change is confirmed. Downgrades take effect at the start of the next billing cycle, maintaining the current tier's benefits until the end of the paid month.
Yes. There is no commitment contract and no cancellation fee. You cancel directly on the site, without needing to contact support.
After cancellation, you keep access until the 30 days of the plan are completed. Your characters and progress are saved for up to 90 days, allowing reactivation without data loss. Adventures purchased separately remain permanently accessible, independent of an active subscription.
Yes. You can pause the subscription for up to three months without cancelling. During the pause, billing stops and access goes into read-only mode: you can view lore and character sheets, but cannot host sessions.
The pause exists so you don't have to cancel during travel, vacation or busy periods. When you resume, everything is back as it was. If you need a short break and don't want to lose progress or founder benefits, pausing is the right path.
A refund is guaranteed for up to 3 days after billing, with no bureaucracy. Just contact us via the official Discord or at support@erderon.com. After 3 days, proportional refunds for unused periods are not granted.
The 3-day window exists so you can try the platform safely before deciding whether to continue. If for any reason the experience didn't meet your expectations, just report it and the amount is refunded. After that period, the month is billed in full because the delivered content, adventures, lore documents and grid access, has already been made available.
Yes. Early supporters of the pre-alpha have benefits that will not be available after the early access window closes: permanent THE FIRST 100 badge, name in the official credits, early access to new features and a place within the Erderon universe.
The THE FIRST 100 badge is permanent recognition for those who believed in the project before version 1.0. Lorde tier supporters among the first have the opportunity to receive a custom NPC created by the team with their story inserted into the universe's canon. These benefits do not return after the early access window closes or reaches 100 supporters in Brazil and 100 more globally.
No, but the current pre-alpha requires a dedicated graphics card. Non-gaming laptops from 2015 with a dedicated GPU ran the system without issues in internal tests. Support for onboard graphics cards is on the roadmap and will arrive soon.
Minimum configuration (pre-alpha):
Recommended configuration:
The 3D grid is a medieval environment rendered in real time where characters and monsters move in turns, with initiative tracking, movement range calculation and area-of-effect visualization. Grids come ready-made with each adventure, with no need to build anything.
The central difference from other 3D grid tools on the market is exactly this: in Erderon, the GM doesn't build the map tile by tile. Grids are created by the art team for each scene of each adventure, with visual and lore consistency. Erderon is for playing. Other 3D grid tools are for building.
In the current pre-alpha, up to five players plus the GM per table. In version 1.0, this limit increases, covering the vast majority of D&D groups.
The five-player limit in the pre-alpha reflects the current capacity of the infrastructure under development. Most D&D tables have between three and six players, so the current version already covers the majority of groups. In version 1.0, the co-GM feature will also allow two assistant GMs to help manage larger tables.
The system has automatic reconnection for drops of up to 30 seconds. For longer drops, login is required again. Progress is saved automatically every two minutes.
If the GM disconnects, the session pauses automatically while players wait for up to five minutes. After that period, the session ends, but all progress is saved. Players who lose connection can return without losing their character state or adventure progress.
There are two channels: logged in and not logged in. After logging in, access the member area and click on Tickets. Without login, the main channel is the official Discord, with responses within two hours during business hours. The email contact@erderon.com has a 24 to 48 hour response time.
In practice, the team responds to 100% of users within 24 hours, regardless of the day of the week. Bugs reported by the community are classified by severity and fixed within 72 hours for non-critical issues. The Discord also has a dedicated channel for suggestions, reviewed weekly by the team.
Yes. The official Discord is the community hub, with channels to find groups, GM tips, roleplay, art and development feedback. The team makes exclusive announcements and hosts live events directly on the server.
The Discord has dedicated channels for those looking for a table and for GMs who need players, making it easy to form groups even for those who don't have friends who play RPG. The team holds monthly live events, including gameplay sessions with the creators, lore reveals and Q&A sessions.
Yes, and the team actively encourages it. Gameplays, reviews, tutorials and critiques are all welcome, and the content can be monetized normally, including YouTube ads and Twitch bits.
The only request is that the creator makes clear that Erderon is in pre-alpha, to align expectations for those discovering the platform through content. Creators with consistent engagement can request a free access key for content production. An official creator program, with additional benefits and early feature access, is planned for the 1.0 launch.
Yes. Charging your players to GM using Erderon is permitted by the Terms of Use. Professional GMs can host paid tables, sell spots in their campaigns and monetize gameplay streams normally.
What is not permitted is reselling access to the platform itself or redistributing Erderon's official adventures. The content you receive as a subscriber is for use at your tables, not for commercial redistribution. Beyond that, Erderon is a work tool like any other.
Yes. The GM uses Erderon on a laptop and projects to a TV or projector. Players around the table use physical sheets or D&D Beyond. It works well as a visual aid for in-person sessions.
The 3D grid works as the battle map that everyone sees on screen, with the GM controlling tokens from the computer. The interactive map is especially useful for showing geographies, cities and the world's political situation to in-person players. An optimized in-person mode is on the roadmap for future versions.
The target for version 1.0 is Q4 2026. The pre-alpha relaunch with significant improvements is planned for May 2026. The pace of development depends directly on growth in the subscriber base.
The roadmap divides development into quarterly milestones throughout 2026. Integrated character sheets arrive in Q1. Fog of War and dynamic lighting in Q3. The official 1.0 launch closes the year. The more supporters, the faster each milestone can be developed.
Yes, starting with version 2.0. The systems with the highest demand are Ordem Paranormal, Pathfinder 2e, Vampire: The Masquerade, Call of Cthulhu and Tormenta 20. The order of implementation will be voted on by the community after the 1.0 launch.
Each new system in Erderon will not come as just a rules adaptation. The proposal is to create a complete setup for each system, maintaining the ready-made world philosophy. Support for Vampire, for example, would not mean just adapted character sheets, but the full mechanics and possibly adapted storylines.
It is still being studied. Research exists on a marketplace integrated with the Adventure Builder, where creators would submit adventures for team approval before publication. For now, we do not have a final answer on the matter.
If implemented, creators with higher sales volume would receive a special badge, homepage prominence and a higher revenue share percentage. Content would need to be original and free of copyright violations. The technical and commercial viability is still being evaluated.
Not in the current pre-alpha. The focus is exclusively on ready-made content. In version 1.0, we will begin working on the feature that will allow creating complete adventures with maps, encounters, NPCs and narrative.
The decision not to include the adventure editor in the pre-alpha was intentional. The MVP prioritizes the experience of playing well before adding creation tools. When the Adventure Builder arrives in 1.0, it may come with ready-made templates by adventure type and a CR system calculated automatically for encounters.
Yes, but initially not as a full gameplay platform. The mobile app planned for future versions will be focused on players, not GMs: viewing character sheets, rolling dice, following table chat and receiving session notifications. Hosting sessions will remain a desktop function.
A phone screen is too small for the 3D grid and for the amount of information a GM needs to manage during a session. The current focus is delivering an impeccable desktop experience before dividing attention with mobile. After that, we will study the feasibility of a full mobile platform.
Erderon is an independent project sustained 100% by community subscriptions, with no outside investors. The operational break-even requires a subscriber base of between 600 and 1,000 subscribers. Long-term sustainability begins at 2,500 to 3,000 subscribers. Each subscription matters directly.
Transparency about this is part of the commitment to the community. The project was launched with the founders' own investment. We have no investor pressure for quick returns and no obligations that compromise the creative integrity of the project. Each person who subscribes directly funds the delivery of next month's adventures, the development of upcoming features and the survival of the platform.
That is not in the plans. Erderon was created by tabletop RPG game masters for tabletop RPG game masters, and the intention is to maintain that independence. No sale conversations are being conducted.
The honest answer is that the future is not set in stone. But the only goal today is to build the best online tabletop RPG platform in the world. Selling the project before achieving it would mean abandoning the dream before its time. The community of supporters is the reason Erderon exists, and any relevant decision about the future would be communicated with full transparency.
100% of resources go to development, content, infrastructure and marketing. There are no outside investors receiving returns. Every dollar raised goes back into the platform.
The approximate distribution of resources is: 50% on development, including programmers and designers; 25% on content creation, with writers and artists; 15% on server infrastructure and tools; and 10% on marketing and community. This model ensures that subscriber base growth translates directly into more content and features, not shareholder profit.
